Determination of adulterants in suspected liquor samples using chemical tests

Abstract

The term alcohol, used as a proper name, is applied both to the absolute substance farther specified by chemists as ethyl alcohol, and to its mixtures with smaller proportions of water and slight proportions of other substances. In chemistry, the word alcohol is used as a common or generic name to designate several series of substances. Alcohol consumption has existed in India for many centuries. The quantity pattern of used and resultant problems have undergone substantial changes over the past twenty years. This category, created for revenue purposes, consists in western- style distilled beverages such as whisky, rum, gin. These are made in India under government license and the maximum alcohol content allowed is 42.8%. Besides licensed distilleries, a number of small production units operate clandestinely. The raw materials they used are similar to those in country liquor, but since they evade legal quality controls the alcohol concentration in their products varies and adulteration is frequent. It is common to rum, whisky and gin find samples containing up to 56% alcohol. The hazardous adulterant is industrial methylated sprit which irregularly cause mass toxicity of humans who lose their lives or suffer irreversible eye damage. Since no government revenues are paid, illicit liquor is considerably less expensive then license country liquor, and thus finds a ready market among the poor.
